I have that problem with starter kits. I'm trying to build a library of SMD resistors, for instance. The only kits I find are either high tolerance (5% film, nah...), or have way too many values. (I don't need 1.2 and 1.22k.. if I do, I'll order them specifically.) So, it's back to Digikey ordering each value in a series, but then I see the steep discount at quantities and I find myself ordering 100 each of 20 values and holy cow the costs add up. :-)
Niiiice. Although I have to assume those aren't thin film. Not sure how much difference it makes, but I hear they're "quieter" for audio use. For a penny apiece, I might start here though. Thanks for the link.
